Changes the icons associated with the display (window).
Multiple icons can be provided for use in different contexts, e.g.
window frame, taskbar, alt-tab popup.
The number of icons must be at least one.

provided then one of the bitmaps will be scaled up or down to the
required size.
The choice of bitmap is implementation dependent.
